Saving Mr Banks - watch Tom Hanks in the trailer for a film about the making of Mary Poppins

In 1961 PL Travers, the author of Mary Poppins, traveled to California to discuss the film adaptation of her book with Walt Disney. John Lee Hancock's film shows the rocky relationship between the pair, as Travers (played here by Emma Thompson) gradually reveals to Disney (played by Tom Hanks) that the origins of the book lie in her own difficult childhood. Saving Mr Banks is released in the UK on Friday 29 November, Friday 20 December in the US and boxing day in Australia
